OAOD (Specto)

Specto is a desktop application that will watch configurable events
(such as website updates, emails, file and folder changes, system
processes, etc) and then trigger notifications.

For example, Specto can watch a website for updates (or a syndication
feed, or an image, etc), and notify you when there is activity
(otherwise, Specto will just stay out of the way). This changes the
way you work, because you can be informed of events instead of having
to look out for them.
